The Lowdown
G’day, Rusty here. We’ve got a solid, drawn-out run of swell heading for Lakey Pipe, and it’s going to be a busy fortnight for the experienced crew. The pattern settles in from Wednesday the 9th and just keeps rolling, with only a handful of sessions that might be a bit touchy on the tide. No real gap at the start—we’re straight into it.
Wednesday morning the 9th kicks things off with a serious 8 ft SSW groundswell, period a long 16 seconds. The combined energy is pumping hard at 3504 (moderate to strong), and while the wind is a 9 mph cross-off from the SSE, it’s keeping the faces clean. Water temp is 80°, dead on normal for this time of year—no surprises there. This is expert territory at that size, but the reef will be handling it beautifully. Thursday the 10th holds similar, with a 6 ft to 7 ft SSW swell and period stretching to 17 seconds on the arvo—still cross-off winds, still clean. Friday the 11th is more of the same, 7 ft to 7 ft SW, 15-16 second intervals. Saturday the 12th drops a touch to 5 ft SW, but the cross-off wind stays and the morning session looks excellent. Sunday the 13th picks back up to 6 ft in the morning, jumping to 8 ft SW in the afternoon with a very long 18-second period—solid groundswell energy (3693 in the arvo). That long period will make the reef really stand up.
We roll into the second week with more consistency. Monday the 16th has a 6 ft to 6 ft SW swell, clean under 9 mph winds. Thursday the 17th holds 6 ft SW, 14-second period, still cross-off and clean. Friday the 18th drops to 5 ft SW in the morning with light breeze, then jumps to 7 ft SSW in the afternoon. The standout window kicks off around Sunday the 20th: 6 ft SW in the morning with 18-second period, building to 8 ft SW in the arvo (2845 combined energy). Monday the 21st sees 7 ft SW under light 6 mph cross-off winds—that’s about as good as it gets for this setup. But the real headliner is Wednesday the 23rd: 7 ft to 8 ft SSW, 17-second period, light winds, and the combined energy hits 3929 in the afternoon—this is the pick of the whole run. Thursday the 24th pushes 10 ft SSW, which is too big for this break, even for experts—so that’s a skip.
Course, Lakey Pipe is consistent and exposed to SW swell, but it’s a reef and it can get crowded—crowds are listed as “often,” so expect company on the good days. The wind stays cross-off for the entire forecast, no true offshore, but it’s clean all the way through. For the experienced surfer, this is a rare long block of quality. If you can only paddle out once, make it Wednesday the 23rd morning or afternoon—that’s the one.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
